CARBlD-FEEDING DEVICE.

SPECIFICATION forming part of Letters Patent N0.'784,811, dated March 14, 1905.

Application filed June 20, 1904. Serial No. 213,300.

.1 0 all whom, it may concern:

Be it known that I, IVILLIAM SINCLAIR, of San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful Improvements in Carbid-Feeding Devices; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in acetylene-gas-generating apparatus; and its object is to provide a simple device whereby the calcium carbid can be supplied to the generating-chamberwithout danger of gas escaping from the 'holder or loss or waste of material and in such manner that after the carbid is exhausted the waste can be withdrawn without fouling the apparatus.

The device is of such nature that a predetermined charge of carbid can be readily inserted in the generating-chamber at will without the manipulation of any valves or closures in the apparatus and without disturbing the gasometer-bell. i

The invention consists in a novel carbid holder and support whereby the holder can be introduced mouth downward into the generating-chamber through a water-sealed opening and then the holder raised inside the water seal and opened, permitting water to enter the holder and the gas to escape into the gasometer-bell.

The invention will be described in detail, with reference to the accompanying drawings, and the features for which protection is desired are summarized in the claims.

In the drawings, Figure 1 is a vertical sectional elevation of a complete acetylene-gasgenerating apparatus, showing the carbidholder in operative position. duced transverse section on line 2 2, Fig. 1. Figs. 3 and 4: areside and sectional elevations of the carbid-holder.

A designates the carbid-holder, which is preferably tubular in form and has a flaring open mouth a at one end and is closed at its other end and provided with a shank a, by which the holder is pivoted on the end of a handle B. On the other end of the handle B Fig. 2 is a re.

gles to handle ii) the holder A is approxi-' mately in line with the handle; but when lever G is turned to the position shown in Fig. 1 (approximately parallel with handle B) the holder A is swung upward, so that its mouth is elevated above the pivot of shank a to handle B.

The mouth (6 of the holder may be closed by a valve E, which is preferably attached to one end of a rod F, that is bent back toward the handle B and has its other end slidably confined in a slot 5 in the handle. The parts are so proportioned that when in the position shown in Figs. 3 and at the valve E closes the mouth of the holder, but when in the position shown in Fig. 1 the valve is unseated. The valve E may be confined between nuts ff on the rod, which permit of the valve being adjusted to properly close or open the holder when in the various positions indicated in the drawings.

In order to more readily explain the operation of the holder, I have shown in Figs. 1 and 2 the preferred form of apparatus or gasometer I employ therewith. GIS the gasbell, which may be suitably weighted and is preferably water-sealed between the double walls of the tank H, which has a false bottom H, below which may be arranged a chamber 1 for fresh carbid, said chamber being provided with a door which should be constructed to close sufiiciently tight to prevent moisture contacting the earbidf Another chamber, J may be used for the spent carbid refuse, and another chamber, K, may be provided to contain the holder when not in use. This chamber K may have a rod Z: in it to facilitate cleaning out the holders. At one side of the gasometer and below the bell is a generating-chamber L, which extends outside of and below the double walls of the gasholder H, the water in the chamber forming an effective seal to prevent escape of gas from the holder through the generating-chainber. This generating-chamber may be open at top both outside and inside the gasometer, as shown. t

The mode of using the carbid-holder and apparatus is as follows: A quantity of fresh carbid is placed in the holder A, and then the parts are turned into position indicated in Figs. 3 and 4, so that the holder is closed by the valve E. Then the holder is inserted mouth downward into the outer leg of the generating-chamber, and when it reaches the bottom thereof lever U is pulled so as to turn the holder upward into the position shown in Fig. 1, so that it projects up into the inner leg of the generating-chamber. This movement of the holder causes the unseating of valve E and permits water to enter the holder and contact the carbid, and the resultant gas escapes upwardly into the gasometer, while the spent and waste earbid remains in the holder. The holder can be suspended by catching the hooked end a of the lever C over the edge of the outer wall of the generatingchamber, as shown in Fig. 1, until the carbid is spent. \V hen it is desired to remove the holder, the handle is lifted and lever C thrown back until the holder is brougl'lt into alinement with the handle, which movement produces the automatic closing of valve E, so that the spent carbid is retained in the holder while being removed from the generatingchamber and can be emptied where desired.

The simplicity of the carbid-charging device is obvious. No manipulation of valves is required, the holder can be removed and replaced in the generating-chaml )er readily, and no skilled workman or special knowledge of the apparatus is required. to operate it.

I do not consider the valveE indispensable; but it is advantageous to use it both to prevent water contacting the carbid until the holder is fully entered within the inner leg of the generating-chainber and to retain the spent carbid when the holder is removed.

The slot 6 in the handle permits the valve E being entirely withdrawn from the end of holder when placing carbid therein or when it is desired to cleanse the holder or let it dry out.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is

1. A charging device for acetylene-gas-generating apparatus, comprising a handle, a carbid-holder pivoted to one end of the handle, a lever pivoted to the other end of the handle, and connections between said lever and holder, whereby the holder can be held in alinement or at an angle to the handle, substantially as described.
